<p>Device for feeding work (U) to machine tool comprising a work table (11) and an air float (14) in a water vessel (15) and connected with said table by a rod (12) so that said work is pushed up against the tool (WL) as working proceeds.</p><p>In one embodiment, a manometer (19) for detecting air pressure in said buoy is so arranged that when detected air pressure is deviated from preset value, a signal generated therefrom may control pump-valve means (23, 24) for supplying water into said vessel (15).</p><p>In another embodiment, a second rod (33) arranged to be in parallel to said first rod (12) to be vertically moved upward in a preset rate and a load cell (39) arranged between said two rods in such a way that when electrical resistance thereof is deviated from a preset value, a signal generated therefrom may control air pressure in said air float (14).</p> |
